Answer: b
Explanation: The complete solution for the current is the sum of the complementary function and the particular integral. The complete solution for the current becomes i = ce-200t + 0.98cos⁡(1000t+π/2-78.6o).

8. The current flowing through the circuit at t = 0 in the circuit shown in the question 5 is?
a) 1
b) 2
c) 3
d) 0View Answer

Answer: d
Explanation: At t = 0 that is initially the current flowing through the circuit is zero that is i = 0. So, i = 0.

Answer: a
Explanation: The complete solution for the current is the sum of the complementary function and the particular integral.
So, i = [-0.98 cos⁡(π/2-78.6o)] exp⁡(-200t)+0.98cos⁡(1000t+π/2-78.6o).
